The difference between macronutrients and micronutrients comes down to quantity and function in the body:
π½️ Macronutrients
These are nutrients your body needs in large amounts to provide energy and support major functions like growth, repair, and movement.
The 3 Main Macros:
| Macronutrient | Role | Sources |
|---|---|---|
| Carbohydrates | Main source of energy | Fruits, grains, veggies, legumes |
| Proteins | Builds and repairs tissue, enzymes, hormones | Meat, eggs, dairy, beans, tofu |
| Fats | Supports brain health, hormones, energy storage | Avocados, nuts, olive oil, fatty fish |
π‘ Alcohol provides calories (7 kcal/g) but is not considered a macronutrient.
π Micronutrients
These are nutrients needed in smaller amounts, but they're essential for proper body functioning, including immunity, bone health, metabolism, and more.
Micronutrient Types:
| Type | Examples | Functions |
|---|---|---|
| Vitamins | A, B-complex, C, D, E, K | Vision, immunity, energy metabolism, blood clotting |
| Minerals | Iron, calcium, magnesium, zinc, potassium | Bone strength, oxygen transport, nerve function |
✅ In Summary:
| Feature | Macronutrients | Micronutrients |
|---|---|---|
| Needed in | Large amounts | Small amounts |
| Provides energy? | Yes (calories) | No |
| Key roles | Energy, structure, function | Enzyme function, immunity, growth |
| Deficiency signs | Fatigue, muscle loss, weakness | Cramps, poor immunity, brittle bones |
